But we know that some of the best parts of every festival come from hallway conversation and social interaction, so we've left most of Friday open for what we're calling "XOXO Social" — a shorthand for a series of events around town, your chance to experience the first day of the Market and our food carts, and an opportunity to meet and explore Portland other 'XOers. Here's a list of all the social events on Friday, as well as the other unofficial events this weekend!

Friday

2:00pm-5:00pm — Ground Kontrol Freeplay Freekout.Ground Kontrol is one of the best retro-gaming arcades in the world, set in a retro-future bar. 90 classic arcade games and 26 pinball games, all set on free play, thanks to PIE, Silicon Florist, and Metafilter. XOXO badgeholders only! 511 NW Couch St at NW 5th.

2:00pm-5:00pm — Ice Cream Social at Panic Inc. Like modern-day Willy Wonkas, the crew at Panic have been making world-class Mac and iOS software forever, but rarely let anyone inside their factory. Today, that changes. Join Cabel, Steve, and the Panic gang for ice cream and drinks at their first-ever open house, and try to find the secret rooms, subtle videogame references, and Mario-meets-Toontown rooftop deck. 315 SW 11th Ave at Burnside.

5:00pm-6:30pm — XOXO Rooftop Party at Wieden+Kennedy. After you've had your fill of pinball and vintage Apple hardware, head over to W+K's amazing office for a rooftop party with food carts, drinks, and a performance by the Wanderlust Circus. Don't be late for your meeting in The Basket. XOXO badgeholders only! 224 NW 13th between Everett and Davis.

Saturday

6:00pm-late — Kickstarter Meetup at Dig A Pony. Join the team from Kickstarter for a drink at Dig A Pony, the lovely bar where XOXO was conceived, and one of the five stops on the XOXO Pub Crawl. RSVP requested at rsvp@kickstarter.com. An easy ten-minute walk from the YU Contemporary. 736 SE Grand at Morrison.

Sunday

8:00pm-2:00am — Etsy's XOXO After Party at Union/Pine! After XOXO's over, head over to celebrate at Union/Pine, with drinks, snacks, and live performances from pocketknife, Craft Spells, and DJ JD Sampson (from Le Tigre). 21+ only, free admission. 525 SE Pine at Grand.

Partner Events

September is festival month in Portland, and we've teamed up with the other major events this weekend to run a continuous free shuttle between them on Saturday and Sunday. The shuttle runs every 20 minutes from 9am to 7pm, and hourly from 7pm to midnight, picking up at the Westin Downtown and stopping at XOXO.

Before 7pm on Saturday and Sunday, the shuttle also stops at these three events worth checking out.

Time-Based Arts Festival (Wednesday-Saturday). A five-minute walk from the YU Contemporary, TBA's The Works occupies the abandoned Washington High School, turning it into an interactive art gallery with classrooms converted into exhibits. It's completely free and open to the public, just walk right inside the front doors located at SE Stark and 13th. This is the last year TBA will be at Washington High, so see it while you can.

Portland Mini Maker Faire at OMSI (Saturday-Sunday). A two-day, family-friendly friendly showcase of creativity and cool tech, with exhibits, talks, demos and performances. Located at Oregon's Museum of Science & Industry in SE Portland. 10am-6pm, $12 for adults and $8 for ages 3-13. See the full schedule on their website.

Fabrication Fest at ADX (Saturday-Sunday). You'll see ADX's stamp all over XOXO, from our cafe countertops in the market and Kickstarter's booth to the huge fabricated signs hanging overhead and on the stage. ADX is opening the doors to their 10,000 sq. ft. workshop and gallery space, and showing off their posse of physical hackers and makers, only a five minute walk from the YU Contemporary.
